Optimization and experiment returns null page

Hi,

My website uses a authentication header. I setHeader in custom scripting and successfully ran the test.
WPT gave me few sugeestions for optimization and options to perform some experiments (e.g. inline script, defer js/css, preload images etc). I ran the experiment and I got a blank page in response ( probably its not picking the auth header). How to address this situation?

Hello Mark,

I regret to inform you that the script is currently incompatible with experiments. This is due to potential interference with the way experiments are executed.

Best regards,
Atib
